Patlite LR7 Series Signal Towers — 70mm LED, Pre-Assembled
PatlitePatlite LR7 Series 70mm LED Signal Towers — Pre-Assembled
The Patlite LR7 series is the largest-diameter tower in Patlite's modular LR signal tower family, delivering the brightest, most uniform 360° visual signaling of any LR model. This page contains every factory-assembled LR7 tower configuration available through Automation Distribution — ready to install, pre-wired with a 3-meter cable, and shipped in the exact tier and color combination ordered.
If you need to build a custom LR7 configuration or replace an LED tier, base unit, or buzzer module on an existing tower, shop LR7 Components & Modules instead.
What is the LR7 Series?
The LR7 is Patlite's 70mm LED signal tower — the largest of four diameter options in the LR series (LR4 at 40mm, LR5 at 50mm, LR6 at 60mm, LR7 at 70mm). The larger diameter delivers substantially more light output per tier than smaller LR models, making the LR7 the default choice for installations where the tower must be visible across a large production floor, warehouse, or outdoor-sheltered area.
Every LR7 assembly is built on the same "Twist and Lock" modular architecture: a base unit at the bottom, stackable LED light tiers in the middle (Red, Amber, Green, Blue, or White), and an optional buzzer module at the top. Pre-assembled assemblies ship as a single factory-configured SKU — no field assembly required. The 3-meter pre-wired cable terminates in flying leads ready for PLC, relay, or panel termination.

How to Read the LR7 Model Number
Example: LR7-302WJBW-RYG
- LR7 — 70mm LR series signal tower
- 3 — Number of LED tiers (1, 2, 3, 4, or 5)
- 02 — 24V DC rated voltage
- WJ — Direct mount with cable
- B or N — B = with buzzer, N = no buzzer
- W — Off-white body (standard for pre-assembled)
- RYG — Color stack from top to bottom (Red, Amber, Green)

Typical Applications
- Machine tool status — Run / fault / call-for-service indication on CNC machining centers, turning centers, and EDM equipment
- Robotic cell signaling — Robot operational status, safety interlock state, and cycle completion
- Conveyor & packaging lines — Fault, jam, and end-of-cycle alerts on long production lines where Ø50mm towers are too small to see
- Warehouse andon — Order-pick status, shortage alerts, and supervisor-call signaling
- Material handling — Forklift staging, conveyor merge/divert status, and AGV path signaling
- Outdoor-sheltered installations — IP65 protection handles dust and water-jet exposure common in food processing, loading docks, and yard operations
Frequently Asked Questions
What's the difference between LR7 and LR6?
The LR7 is 70mm in diameter; the LR6 is 60mm. Both run on 24V DC and use the same "Twist and Lock" modular architecture, but the LR7 produces noticeably brighter output per tier due to the larger lens and LED assembly. Choose LR7 when the tower must be visible across a large area (100+ feet) or in high-ambient-light environments. Choose LR6 when panel space is limited or the viewing distance is shorter.
Can I add or change LED colors after installation?
Yes. The LR7's "Twist and Lock" modular design allows any tier to be removed, replaced, or added without rewiring. Buy individual LED modules (LR7-E-R, LR7-E-Y, etc.) from the LR7 Components & Modules page. Note: tiers must be removed sequentially from the top down to protect internal connections.
What's the audible output of the LR7 buzzer?
The LR7 buzzer produces 90dB at 1 meter — the loudest of the LR-series buzzers (LR4/LR5 are 85dB, LR6 is 88dB). It's audible over typical plant ambient noise without being overpowering. Models with "BW" in the part number (e.g., LR7-302WJBW-RYG) include the buzzer factory-installed at the top of the stack.
Is the LR7 available in 12V DC or AC voltage?
No. The LR7 series is 24V DC only. For 12V DC or AC operation, consider the LR4, LR5, or LR6 series which offer additional voltage options. Contact Automation Distribution if you need help selecting an alternative.
Can the LR7 be pole-mounted or wall-mounted?
All pre-assembled LR7 models on this page use direct mount with cable (WJ type). For pole-mount or wall-mount installations, purchase an alternative LR7 base unit from the LR7 Components & Modules page, plus the LED tiers and accessories (pole, bracket) needed for the configuration.
